MEMORANDUM ***
Martin Alvarado Guzman and Amparo Alvarado, husband and wife and natives and citizens of Mexico, petition pro se for review of the Board of Immigration Appeals’ orders affirming without opinion an immigration judge’s (“U”) decision denying their applications for cancellation of removal. To the extent we have jurisdiction, it is conferred by 8 U.S.C. § 1252. We review de novo claims of constitutional violations in immigration proceedings. See Ram v. INS, 243 F.3d 510, 516 (9th Cir. 2001). We dismiss in part and deny in part the petition for review.
We lack jurisdiction to review the agency’s discretionary determination that petitioners failed to show exceptional and extremely unusual hardship. See Martinez-Rosas v. Gonzales, 424 F.3d 926, 929-30 (9th Cir.2005).
*486To the extent petitioners contend the IJ violated their due process rights by ignoring a psychological evaluation of their son, the contention is not supported by the record and does not amount to a colorable constitutional claim. See id. at 930 (“[t]raditional abuse of discretion challenges recast as alleged due process violations do not constitute colorable constitutional claims that would invoke our jurisdiction”).
Petitioners’ equal protection challenge to the Nicaraguan Adjustment and Central American Relief Act (“NACARA”) is foreclosed by our decision in Jimenez-Angeles v. Ashcroft, 291 F.3d 594, 602-03 (9th Cir. 2002) (“Congress’s decision to afford more favorable treatment to certain aliens ‘stems from a rational diplomatic decision to encourage such aliens to remain in the United States’ ”). Petitioners’ due process challenge to NACARA also fails. See Hernandez-Mezquita v. Ashcroft, 293 F.3d 1161, 1165 (9th Cir.2002) (rejecting a due process challenge because petitioner failed to demonstrate that he was deprived of a qualifying liberty interest).
PETITION FOR REVIEW DISMISSED in part; DENIED in part.
This disposition is not appropriate for publication and may not be cited to or by the courts of this circuit except as provided by 9th Cir. R. 36-3.
